Maytag Dryer Error Code LdS

LdS stands for lower dryer door sense error. It means the control board is not receiving a valid signal from the lower dryer door switch, which causes the control board to disable the lower dryer cycles and lower dryer display as a precaution. The fault can be caused by a defective door switch, loose wiring connections, or power line interference. The lower dryer will remain disabled until the diagnostic code is manually cleared.

The LdS code specifically disables the lower dryer compartment, so the lower dryer cannot be operated while the fault is active. The upper dryer compartment is not referenced as affected by this code. You should not attempt to bypass the door switch fault, as the door switch is a safety component that prevents the dryer from running with an open door.

Repair costs vary depending on the root cause. If only a door switch replacement is needed, parts typically range from around $15 to $50, with additional labor costs if a technician is hired. Control board replacement is more expensive, with parts generally ranging from $100 to $300 or more depending on the model. If the fault is caused by power line interference and no parts are needed, the only cost is the time spent diagnosing and clearing the code.

Start by inspecting the lower dryer door switch and all wiring connections leading to it for damage, corrosion, or loose connectors. Test the door switch with a multimeter to verify it has proper continuity when the door is closed. If the switch and wiring are in good condition, the issue may be power line interference, in which case manually clearing the code may resolve it. If the error returns after clearing, the door switch or control board may need to be replaced.

The LdS code must be manually cleared through the diagnostic mode rather than through a simple power reset. If the underlying cause is power line interference rather than a hardware failure, clearing the code manually may fully resolve the issue. However, if the door switch or wiring is defective, the code will return after clearing until the faulty component is repaired or replaced.
